How to Help Prevent Swimmer’s Ear
Evidence-based steps to reduce swimmer’s ear risk, recognise warning signs and avoid unsafe ear-cleaning or drying practices.
Key point
Let water drain, dry the outer ear gently and do not insert cotton buds or other objects into the ear canal. Ask a healthcare professional before using drying drops, especially with ear tubes, a perforated eardrum, drainage or current infection.
What swimmer’s ear is
Swimmer’s ear is an infection of the outer ear canal. Water that remains in the canal can weaken the protective skin and wax environment, allowing bacteria to multiply.
After swimming
- Tilt the head so each ear faces down and allow water to drain.
- Dry the outer ear with a towel.
- If needed, use a hair dryer only on its lowest heat and fan setting, held several inches away.
- Keep objects and fingers out of the canal.
Earplugs and drops
A bathing cap, earplugs or custom swim moulds may help some swimmers keep ears dry. A poor fit may irritate. Ear-drying drops are not appropriate for everyone; check with a healthcare provider.
Get medical advice for symptoms
Ear pain, itch, redness, swelling or drainage can need treatment. Do not keep swimming or self-treat with unverified drops when infection or eardrum damage is possible.
Sources and review basis
Singapore’s HealthHub explains that frequent swimming and prolonged moisture can weaken the ear canal’s protective barrier, while Singapore’s humidity can add to the risk. Follow its local guidance on external ear infection and the CDC’s swimmer’s ear prevention guidance. Seek individual medical advice for symptoms or before using ear drops.
Common questions
Why can frequent swimming cause swimmer’s ear?
Water left in the ear canal can soften its protective skin and wax barrier, making infection easier. HealthHub notes that frequent swimming and prolonged moisture increase risk, and Singapore’s humid climate can contribute.
Should I use cotton buds to dry inside my ears?
No. Do not insert cotton buds, fingers or other objects into the ear canal. They can damage the skin or push wax deeper. Let water drain and dry only the outer ear gently.
When should a swimmer seek medical advice for ear symptoms?
Seek medical advice for ear pain, discharge, marked swelling, severe itch, dizziness, or symptoms that persist or worsen. Do not use unverified drops if an eardrum injury, ear tubes or infection may be present.
